MEANS FOR DYEING, BLEACHING, AND TREATING LIVING HAIR Ruth Samel andMinna Wotzilka, London, England, assignors to Ernest Norland, London,

England Application March 31, 1949, Serial No. 84,764 In Great BritainOctober 18, 1947 This invention relates to improved means for dyeing,bleaching or treating living hair.

The invention mainly consists in a comb or brush for dyeing, bleachingor treating living hair made of a mass being cut to form a comb or cutinto comparatively thin bars or rods suitably attached to a backing toform a brush. The elongated elements thus produced, when made into acomb or a brush, are free at one of their ends and mounted in a base attheir other ends in generally aligned relationship. When the comb orbrush is used for dyeing or bleaching the hair the said mass of methylcellulose has incorporated in it a suitable dye or bleaching substance.r

The invention also consists in the masses hereinafter referred to fordyeing, bleaching or treating the hair, used 'in the form of brushes andcombs.

The accompanying single sheet of drawing illustrates, in Figure l, acomb and, in Figure 2, a

brush, as exemplificative of the present invention.

According to one mode of carrying the invention into effect, use is madeof methyl cellulose serving' as a carrier for the dye or bleachingsubstance or other compatible hair treating agent. In addition to beingwater soluble the methyl cellulose is chemically inert, and does notreact with the dye or bleaching substance, and it is tough and elastic;it will not leave a residue of an undesirable nature on the hair.Moreover, the preparation of the dyeing mass in conjunction therewithcan be carried out at ordinary temperatures as the dyes are likely tooxidize at ele vated temperatures. The dyes employed are the usualoxidation dye-intermediates which are commonly used with hydrogenperoxide if it is desired to develop the colour more rapidly. In thecase of bleaching combs or brushes use is made of urea-peroxide as thebleaching agent.

The methyl cellulose is gelatinized with water in which a polyethyleneglycol may be added and in which a compatible wetting agent such as asulpho-succinic ester may be dissolved, and the powdered dye orbleaching substance is admixed therewith. The mass is then rolled intosheets and dried by evaporation at room temperature, preferably in avacuum. The dried sheets are then warmed to about 60 C. and pressed fiatin a press where they are left to cool and then cut to the desired sizesof the combs, the teeth of which are formed by the saw-cut method.

The tips of the comb teeth may be dipped into a suitable varnish so thatthe dye does not come in contact with the scalp. Any of the oxidation 7Claims. (Cl. 13211) acid) dye-intermediates may be used, alone or inadmixture with one another to produce different shades. A small quantityof alkali such as sodium carbonate is also incorporated.

The following is one example for obtaining a suitable mass for dyeingthe hair black: 59 grams of methyl cellulose (the carrier), 20 grams ofpara-phenylene diamine, or sulpho-para-aminodiphenylamine, 5 grams ofsodium carbonate, 300 grams of water, containing 5 grams of Aerosol OT(dioctyl ester of sodium sulpho-succinic The methyl cellulose is firstgelatinized with water and the solid powders are mixed intimately withthe gelatinized mass. The water is insufficient to dissolve more than avery small portion of the dyes.

The following are examples of compositions for brown and blonde hair: 60grams methyl cellulose, 15 grams para-aminophenol, 5 grams para-tolylenediamine, 5 grams sodium carbonate, 300 grams of water (brown hair); 60grams methyl cellulose, 20 grams sulpho-para-aminophenol, 5 grams sodiumcarbonate, 300 grams of water (blonde hair).

Referring to the method of using the comb it is to be pointed out thatdyes require hydrogen peroxide only if a rapid development of colour isdesired. The hair is wetted with water, the comb is applied to the hair,the dye mass dissolves superficially and the dye solution comes incontact with the hair. The hair may then be treated with a dilutesolution of hydrogen peroxide.

In the case of bleaching combs containing urea peroxide the comb isapplied to wet hair.

In the application of the invention to hairsetting the comb or brush ismanufactured as above described, but using only the methyl cellulose andwater, which has the properties of hairsetting when applied to wet hair.A water-soluble perfume may be added, if desired.

Compounds which have hair-waving properties may be incorporated in thecarrier mass. The following is an example; 60 grams methyl cellulose,10- grams sodium carbonate, 15 grams sodium bisulphite, 300 grams ofwater and 5 grams dioctyl ester of sodium sulpho-succinic acid.

The carrier mass of methyl cellulose may also have incorporated in it asuitable hair oil to which oil soluble vitamins may be added, ifdesired. The oil is liberated on to the hair or scalp when the comb orbrush is applied to the wet hair or scalp. Here is an example: 60 gramsmethyl cellulose is mixed with an emulsion of 250 grams water, 50 gramsolive oil and 2.5 grams triethanol-amine. The method of manufactureremains the same as above described.

In the case of the manufacture of brushes the mass referred to is rolledinto sheets and dried, whereupon comparatively thin bars or filamentsare cut therefrom and attached to a suitable backing in mannerswell-known per se.

The back of the comb is preferably provided with a mounting of metal,plastic or other suitable material for the sake of convenient handling.

The masses hereinbefore. described may also be shaped in the form ofsticks or like solid bodies and be used as such for dyeing, bleaching ortreating living hair.

We claim:

1. A device for treating living hair which comprises methyl cellulose inthe form of a plurality of elongated elements free at one of their endsand mounted in a base at their other ends in generally alignedrelationship and a compatible hair treating agent incorporated in themethyl cellulose, said methyl cellulose being soluble and capable ofgelatinizing in water, whereby, when said elements are passed throughhair, the hair is treated.

2. The device of claim 1 wherein the elements are spaced parallel andmounted in a single row, constituting the teeth of a comb.

3. The device of claim 1 wherein the elements are flexible andfilamentary, constituting the bristles of a hair brush.

4. The device of claim 1 wherein a watersoluble dye is incorporated inthe methyl cellulose as a hair-treating agent, said dye being adapted todye hair when applied thereto.

5. The device of claim 1 wherein the plastic material comprises thefollowing components in approximately the proportions by weight of 59parts methyl cellulose, 5 parts sodium carbonate and 20 parts of a blackphenylarnine dye selected from the group consisting of para-phenylenediamine and sulfo-para-amino-diphenylamine.

6. The device of claim 1 wherein the plastic material is adapted totreat brown hair and comprises the following components in approximatelythe proportions by weight of parts methyl cellulose, 5 partspara-toluene-diamine, 15 parts para-aminophenol and 5 parts sodiumcarbonate.

7. The device of claim 1 wherein the plastic material is adaptedto'treat blond hair and comprises the following components inapproximately the proportions by weight of 60 parts methyl cellulose, 20parts sulfo-para-aminophenol and 5 parts sodium carbonate.
